This could be another slugfest similar to the one that took place on Saturday night.

However, if Alvarado couldn't solve Marquez, it stands to reason Rios wouldn't have any better luck. But you never know considering Marquez's age. Every time he fights, he's running the risk of getting old before our very eyes.

The hard-hitting Siberian stopped Alvarado to win the WBO light welterweight title in October of 2013.

He's a former sparring partner of Pacquiao, and he fights an action-packed, crowd-pleasing style.

All of those things make him an attractive opponent for Marquez.

Provodnikov does have a fight scheduled for June against Chris Algieri. Assuming Provodnikov wins, he's got to be at least under consideration as a potential opponent for Marquez.

After winning the IBO and WBA light welterweight titles from KhabibAllakhverdiev in April, Vargas should be a popular name for fighters in the weight region.

Vargas isn't a big name. Though he has some speed, he'd probably be the easiest fight of anyone on this list for Marquez.

It's questionable whether Vargas' name could draw the interest to make the fight worth Marquez's time.

Timothy Bradley

Marquez lost a split-decision to Bradley in October of 2013. He could look to avenge the defeat. Bradley needs an opponent after his loss to Pacquiao left him in limbo and without direction for his immediate future.

Though both are household names, matched together, Bradley and Marquez may not interest many fight fans.

This is perhaps the least desirable fight for Marquez. He'd likely be out-boxed and frustrated again by Bradley's speed.
